EFF lifts the lid on the secrets of the U.S. Army’s chatbots

Thanks to a Freedom of Information request and some further digging, the Electronic Frontier Foundation (EFF) has uncovered just about everything there is to know about the U.S. Army’s chatbot sergeant — including the technology’s past as a tool for catching pedophiles and terrorists on the Web. The revelations are part of EFF’s ongoing investigation into how the military interacts with and collects information from the public over the Internet.

Sgt. Star is the well-known virtual public spokesperson for the United States military, appearing on the Army Careers website and associated Facebook pages to answer questions from potential recruits. EFF has compiled all of his possible responses into a 288-page document that cover all aspects of military service and even the issue of whether soldiers can use umbrellas (yes, in certain circumstances). There’s also a page of usage statistics — Sgt. Star engaged in nearly 600,000 online chats in 2013.

The chatbot was introduced as a cost-cutting measure in 2006, designed to reduce the time that human operators needed to spend on online enquiries — the military estimates that Sgt. Star can do the work of 55 real recruiters. The company behind the bot, Next IT from Spokane in Washington, has also previously developed similar technology for the FBI and CIA in the past. In this case, chatbots were used to engage suspected pedophiles and terrorists, looking for signals that would point to suspicious behavior and allowing a federal agent to monitor 20-30 conversations at once.

EFF believes this kind of activity raises questions about data collection and online monitoring — once again, the balance between the need to catch criminals online and protect the privacy of the ordinary citizen is called into question. “What happens to conversations that aren’t relevant to an investigation, and how do the agencies weed out the false positives, such as when a chatbot misinterprets a benign conversation as dangerous?” asks EFF researcher Dave Maass.

“For all his character quirks, a user would never mistake Sgt. Star for human — that’s just not how he was designed,” continues Maas. “That can’t necessarily be said for other government bots. Military, law enforcement and intelligence agencies have employed virtual people capable of interacting with and surveilling the public on a massive scale, and every answer raises many, many more questions.”

SanDisk’s latest drive sets new benchmark for consumer NVMe SSDs
The SanDisk WD Black SN8100 PCIe Gen 5 SSD with and without heatsink variants

SanDisk has officially introduced the WD Black SN8100, its latest high-end PCIe Gen 5 NVMe SSD targeting PC enthusiasts, gamers, and professional users. With sequential read speeds of up to 14,900 MB/s and write speeds of 14,000 MB/s, the drive sets a new bar for consumer SSD performance, surpassing some of the best NVMe SSDs currently on the market, including the Crucial T705. 

The SN8100 uses a standard M.2 2280 form factor and is available in capacities of 1TB, 2TB, 4TB, and 8TB. It’s worth noting that the 1TB model offers lower write speeds, up to 11,000 MB/s, compared to the higher-capacity versions, which reach up to 14,000 MB/s.

Pairing the RTX 5090 with a CPU from 2006? Nvidia said ‘hold my beer’
RTX 5090.

Nvidia's best graphics cards are often paired with expensive CPUs, but what if you want to try a completely mismatched, retro configuration? Well, that used to be impossible due to driver issues. But, for whatever reason, Nvidia has just removed the instruction that prevented you from doing so, opening the door to some fun, albeit nonsensical, CPU and GPU combinations.

The instruction in question is called POPCNT (Population Count), and this is a CPU instruction that also prevents Windows 11 from being installed on older hardware. Its job is counting how many bits are present in a binary number. However, as spotted by TheBobPony on X (Twitter), POPCNT will not be a problem for Nvidia's latest graphics cards anymore.

AMD’s upcoming CPU could offer bonkers gaming performance
A fake and real AMD Ryzen 7 9800X3D side by side.

AMD's Zen 5 architecture has been a popular choice for gamers due to its outstanding performance and 3D V-Cache capacity, and now a leak suggests Zen 7 could double down on that through a new "3D Core." According to YouTuber Moore's Law is Dead, "[AMD] is moving toward a lot of official variants."

AMD reportedly plans to launch a single overall architecture, divided into different product categories, including the expected lineup: Classic Cores, Dense Cores, Efficiency Cores, and Low-Power Cores. The 3D Core is the latest addition, and it is said to "require full cache chiplets" that "seem to be leading to profound performance increases."
